1. An apparatus for sensing and measuring at least one physiological parameter of a person, the apparatus comprising:

  • a housing comprising a front face, a rear face, and an interior region located between the front face and the rear face, at least a portion of the rear face configured for contact with a targeted area;

    a sensor for sensing at least one physiological parameter, the sensor comprising at least one light source for illuminating the targeted area, at least one optical detector for receiving reflected light from the targeted area, and at least one substrate to which the at least one light source and the at least one optical detector are mounted; and

    at least one optical barrier between the at least one light source and the at least one optical detector, the at least one optical barrier comprising a laterally-extending portion and a vertically-extending portion extending from the laterally-extending portion toward the targeted area, both portions positioned on a same side of the substrate as the at least one light source and the at least one optical detector for preventing direct light transmission from the at least one light source to the at least one optical detector.
